Personal opinion: prepare at least two good competition books and buy classified ones, such as integer part, set part and combination problem. This is thicker, and a topic needs to explain more knowledge. Then look at the basic competition knowledge in front of each part (some may also be helpful to the college entrance examination), and do their examples after reading it. These problems may be difficult for people who are new to the Olympic Games. It doesn't matter if you can't do it. Remember to try the method you can think of, and then look at the answer after reading the analysis, otherwise it will be invalid. The practice of remembering examples is very important. Then do exercises. In fact, I suggest you look for more questions online or prepare more books. Doing more questions is the right way.

The game should be mid-term, and time is running out. If you do well in other subjects, you can focus on it for a while.

In the last week or two, we have to do surprise exercises, and we have to do simulation exercises and test questions every year, focusing on the first volume, because the three big questions in the second volume are really too difficult, which depends a little on personality.

Finally, don't expect too much from the competition, because every year, people who come up with competition questions are different. This year's topic may or may not be suitable for you. In short, you should face all kinds of results calmly. As long as you work hard and are good at math, everything is possible.

You mean reform? Well, if you make a surprise attack, you have to recite many theorems and do many geometric problems. It takes some time to get used to the theorems. I think if you have no experience in this field, it is difficult for you to get a score in geometry, but there are exceptions. I did a 50-point geometry problem in the last semester of Grade Two in Senior High School, which was very simple, but under normal circumstances, this will not happen. Geometry problems must be done, at least 20 yuan. Algebra is more suitable for you, because our junior high school teachers have learned a lot, and this is ok.

Both combination questions and number theory are difficult. Test your logical ability and basic knowledge (number theory needs to remember a lot of common sense of number theory). If you are smart and thoughtful, you can try this type of question, but I don't recommend it if you don't have the basis of competition.

That's all. I hope it will help you.
